Using unit concepts, it is found that:
- a) Grams.
- b) Grams.
- c) Grams squared.
- d) Grams squared.
-----------------------------
- For a data-set, the standard deviation has the same unit as the data-set, both for the sample and the population.
- The variance has the unit squared, both for the sample and the population.
- For example, if the data-set is in metres, the standard deviation will be in metres while the variance will be in squared metres.
-----------------------------
In this question, the data-set is in grams.
- The standard deviation, both for the sample and the population, in items a and b, will be in grams.
- The variance, both for the sample and the population, in items c and d, will be in grams squared.

4/5 is the answer unless you need it in decimal
Answer:
Step-by-step explanation:
Simple interest is
I=Prt, where I= interest, P=principle (initial value), r=interest rate, t=time
I=200(0.052)3
I=$31.20
Answer:
I just want points hahahaha
Based on dimensional analysis and unit conversion theory we conclude that an area of 359 square inches is equivalent to an area of 2.5 square feet.
<h3>How to apply dimensional analysis in unit conversion</h3>
In this question we need to convert a magnitude in a given unit to an <em>equivalent</em> magnitude with another unit. According to dimensional analysis, <em>unit</em> conversions are represented by the following expression:
y = A · x (1)
Where:
- x - Original magnitude, in square inches.
- y - Resulting magnitude, in square feet.
- A - Conversion factor, in square feet per square inch.
Dimensionally speaking, area is equal to the product of length and length:
[Area] = [Length] × [Length]
And a feet is equivalent to 12 inches. Now we proceed to convert the magnitude to square feet:
x = 359 in² × (1 ft/12 in) × (1 ft/12 in)
x = 359 in² × (1 ft²/144 in²)
x = 2.5 ft²
Based on dimensional analysis and unit conversion theory we conclude that an area of 359 square inches is equivalent to an area of 2.5 square feet.
